Scratch

If you put in (9 + 1) the operator will give you 10.

Variables are mostly used for calculator projects like mine. (link to project)

Thanks laptop97.

But I am new so how would I actually write this. Please give me an example.

Are you trying to create a calculator?

Scratch uses operator blocks that you give arguments, which then return your result. These (or any other "reporter" blocks) can be stacked inside of each other to make more complex expressions. The Scratch wiki has a more in-depth explanation on these and other blocks in the "operators" category

Thats right.

For example in Python we can can just write the code:

>>> print 5 + 3
8

And the answer 8 is given.

What is the simplest way of doing this in Scratch?

Thanks for your help.

Does print mean to say it?

Yes it does - the answer is displayed on the screen.

Ok, then it would be

Say(X+Y) for (Z) secs

X, Y and Z are numbers you would put in

So I would have to use variables, right? Where X, Y and Z are variables.

I cannot just do a simple calculation like 3 + 3.

Thats great. Thanks very much.

I think laptop97 already cleared this up, but I'll answer just in case.

You don't necessarily have to use variables, but if you have two constants like that it would be a bit superfluous to do it that way. I'm sure that's just for an example though?

Regardless, I think this is what you're looking for:

But you can also add a variable and a number if you want.

Oh yeah, it's called constant. You can also add a variable and a constant if you want.
